A comparative study of single-layer and multi-layer traffic engineering approaches on transparent optical networks
(IEEE, 2007)This paper comparatively studies single-layer and multi-layer traffic engineering strategies on an IP/MPLS/WDM network. These strategies are evaluated and compared in two different scenarios. In the first scenario, the ... -
Comparison of local and global computation and its implications for the role of optical interconnections in future nanoelectronic systems
(Elsevier, 1993)Various methods of simulating diffusion phenomena with parallel hardware are discussed. In particular methods are compared requiring local and global communication among the processors in terms of total computation time. ... -
Effect of number of burst assemblers on TCP performance in optical burst switching networks
(IEEE, 2006-10)Burst assembly mechanism is one of the fundamental factors that determine the performance of an optical burst switching (OBS) network. In this paper, we investigate the influence of number of burstifiers on TCP performance ... -
Filtering in fractional Fourier domains and their relation to chirp transforms
(IEEE, 1994-04)Fractional Fourier transforms, which are related to chirp and wavelet transforms, lead to the notion of fractional Fourier domains. The concept of filtering of signals in fractional domains is developed, revealing that ... -
Fractional Fourier transforms and their optical implementation. II
(Optical Society of America, 1993)The derivation of a linear transform kernel for fractional Fourier transforms is presented. Discussed in direct relation to fractal Fourier transforms are spatial resolution and the space-bandwidth product for propagation ... -
Influence of phase function on modeled optical response of nanoparticle-labeled epithelial tissues
(2011)Metal nanoparticles can be functionalized with biomolecules to selectively localize in precancerous tissues and can act as optical contrast enhancers for reflectance-based diagnosis of epithelial precancer. We carry out ... -
Interpretation of the space-bandwidth product as the entropy of distinct connection patterns in multifacet optical interconnection architectures
(Optical Society of America, 1993)We show that the entropy of the distinct connection patterns that are possible with multifacet optical interconnection architectures is approximately equal to the space-bandwidth product of the optical system. -
Model-based spectral analysis of photon propagation through nanoparticle-labeled epithelial tissues
(SPIE, 2011)Metal nanoparticles can function as optical contrast enhancers for reflectance-based diagnosis of epithelial precancer. We carry out Monte Carlo simulations to model photon propagation through normal tissues, unlabeled ... -
Object rigidity and reflectivity identification based on motion analysis
(IEEE, 2010)Rigidity and reflectivity are important properties of objects, identifying these properties is a fundamental problem for many computer vision applications like motion and tracking. In this paper, we extend our previous ... -
Optical implementation of the two-dimensional fractional Fourier transform with different orders in the two dimensions
(Elsevier BV * North-Holland, 1995-10-15)Previous optical implementations of the two-dimensional fractional Fourier transform have assumed identical transform orders in both dimensions. We let the orders in the two orthogonal dimensions to be different and present ... -
Optical information processing: Past, present, and future
(IEEE, 2005-09)A historical overview of optical information processing, emphasizing the influence of and interactions with signal processing will be given. Analog optical signal processing, holography, digital optical computing, optical ... -
Photonic magnetic metamaterial basics
(Elsevier, 2010-07-21)In the present study, we provide a detailed analysis for the study of photonic metamaterials. We demonstrate the polarization and orientation dependent transmission response of split ring resonators at the infrared and ... -
Scaling of diffractive and refractive lenses for optical computing and interconnections
(Optical Society of America, 1994-06-10)We discuss both numerically and analytically how the space-bandwidth product and the information density of lenses scale as functions of their diameter and f-number over many orders of magnitude. This information may be ... -
